Isn't this supposed to be a reddit alternative? What's the harm in allowing one or two basic NSFW boards? I think doing so would give the site a ton more users and have people tuning in more frequently.
Once that is allowed, Saidit will compete with Reddit easily! And I can post on Reddit to get people to migrate over here, since I run some nsfw subs over there.
So honestly, we have everything to gain and nothing to lose! Lets allow NSFW content! <3
